Hi,
We have had issues with the CSV file from TD as well. Stripping off the literal text from the cheque # will work but even easier is to change to OFX format. The file isn't easy to read but import works almost every time.
You should consider (with Dan) to revise the import file layout from CSV to OFX (simply or quickbooks format), and then your TD import will fly into BankRec without adjusting the import file.
Best,
Brian
